Looking for some guidance on Stage 1 BKC EDC16

[mmartin191]

I've been getting into Mapping recently and have spent a lot of time on the later version of the ecu, but this seems to be missing many maps that most guides suggest it should have (Drivers Wish for example).

03G906016CB
EDC16
0281011900
371094

Also what would the harm be if i flashed a
VW golf 1.9TDI 105HP 03G906021KH 0281013226 380437
bin file instead?

See attached for OLS / modified bin / original.

Thanks.

Hi, never flash other file not from your ecu if you don't know what you do! You can brick your ecu.

Hi,
for example Audi A3 1.9 tdi pd 105 hp, with EDC16U1 has several different software versions (5347,5497,7640,.....). And if you try to write other flash memory software version without flashing processor memory , you wont be able to start engine. This isn't easy job!
Different versions have different map structure and adresses.
You have mistake in your winols project, I see that you're beginner... do you know what is boost limiter map? X-axis is not MAF value, it is air pressure value (1000 mbar....).

[davorsule]

Also your boost and boost limiter maps are not good!
Turbocharger of this engine can't hold 1,45 bar of boost for longer period.Also limiter is lower than your target boost..Why?

[davorsule]

Torque to Iq map is changed. Why? This is bad activity, avoid doing this. ou can only extend x-axis and calculate iq for higher maf value.

Becuase he do videotutorial tuning, not use brain to understand what is he doing.

Exactly.
Dangerous for engine.

[mmartin191]

Look guys, I said that i'm looking for guidance, so don't lay into me too hard, I'm only learning!
Thanks to those that have helped.

I'm going to make a few edits.

[mmartin191]

I've made quite a few amendments, could someone have a look for me please?

I may look at increasing fueling further, to be on the safe side.

Thanks

[davorsule]

Now:
- boost pressure is good (just maybe you should't change values in 15,20,25 mg)!
- boost pressure limit better now, but don't change last value of x-axis
- from my experience it's useless to change x-axis values in iq limit_maf map you canjust recalculate last column(interpolate), or maybe you know better.

lambda wrong
iq bad not good
turbo wrong all flat percentage
driver wish not touched
some maps not touched
hot and cold start why too much fuel added you can brake camshaft very easy
you need more to learn about remap and to calculate what are you doing

[mmartin191]

Thanks for the recommendations once again davorsule and AVDigitale.

AV - A few questions:
1. Could you point out where the Drivers Wish is? I looked over and over, but couldn't find it anywhere - and i've been unable to find the Damos for it.
2. What are the other maps that are untouched?
3. This file was pulled from my ecu, I realised that EGR had been turned and other areas had been altered, but I didn't realise it had other major changes.

I'll rework from an original so that I know what i've changed.

Thanks.

[AVDigitale]

contact me latter
i send you good tutorial and you will learn

[mmartin191]

Thank you very much, really appreciated.

Yes, agree with AVDigitale. Iq, lambda not good.
you must first learn to find, detect, and read main maps..

[davorsule]

your first DW map is at address= D1A3C, 8x16

[familiozo]

If you need i will upload map pack to find maps easy.

[davorsule]

here you can see two of seven dw maps,
also you can use map packs, but then you will never learn finding map skills

[davorsule]

Look for some maps in 2D view (winols).

Thank you for looking, i'll look into it now.

That would be great thanks.

Thanks for the Screenshots, I'd seen these before, but the rpm on y axis seemed too high and I haven't seen any maps that didn't have the eprom data directly before them (map editing is very new to me)

Here is map pack.

here is what you need ok hit thnx and reputation pass in PM!

[mmartin191]

Thanks for the above files.

I've got a question..
I'm looking to reverse engineer my Air Fuel Ratio and Maf mg/s to output the Fuel Injection quantity.

So you can calculate AFR by the following formula -
Maf (Mg/s) / Fuel Injection quantity (mg) / AFR (your chosen fuel is most efficient at) * 10

I'll give an example.
(500(a)/28.78(b))/14.7(c)*10 = 11.8(d)
Which in my case is the value I want to reverse engineer.
I want to work out what the value of B is, if I know the values of a, c and d. Something that also might come into play is the rpm... 1750(e)

It there anyway that I can get calculate the fuel from the AFR / MAF in the same manor?
(this is probably quite an easy question, but it's late and my brain isn't working)

Thanks

[davorsule]

Formula you wrote isn't good method to calculate injection.

[davorsule]

Must presume and test which AFR value will be the best for engine. Factory adjusted maps are usually the best,
you could compare, but it depends what you want from engine, in which altitude is engine running mostly and other factors.
Try about 16,6 - 17,1 at higher maf,rpm valus.
Then calculate lambda from adjusted afr and at last iq_limit_with maf or map.
Simply first calculate lambda from adjusted afr and then iq with formula.

lambda= AFR/14,5 or 14,7?
lambda=(maf/iq)/14,5
AFR= maf/iq
iq= maf/(14,5*lambda)

I can send you excel table which I made, IF YOU CLICK REPUTATION!

Thank you mate! I spent far too long trying to work out what IQ was equal to. I've added them into my excel spreadsheet, so i'm going to have a crack at it later.

Many thanks!

[davorsule]

Many thanks!

Do you understand calculating lambda and iq from table now?
